If the dyno number would be SAE corrected, it would show about 196 HP. Temperature is higher, but so is pressure against standard, in this case their effects on air density almost cancel each other out.
Correction for temperature only, from 35°C to 25°C would bring us to 206 HP based only on density difference. But turbocharged engine is complex device, different temperature and pressure will have effect both on turbo and intercooler operation to such extend, that corrections can be way off.
IMHO uncorrected numbers with notes for ambient conditions are the right way for turbocharged engines tested on chassis dynos, it would save us many dramas that accompanies internet forums
